Anyone knows if this gpu can handle 4.6k raw workflow? I'm inclined into buying a 1070ti, but this card has 8gb as well and for half the price. I'm sure there's a catch, just wanted to know which one. Here's the card I'm talking about:

I can't comment specifically on that particular GPU's performance, as I haven't followed some up the recent updates (still rocking my 980 TI, which has similiar performance to the 1070 Ti). But I will say that looking at RAM isn't the best way to compare GPUs, as there are things like processor, memory interface, CUDA lanes, etc that also play an important role. It would be like comparing two computers with 16gb of RAM, but one has a top of line i7 processor while the other has a pentium.

The best thing to do would be to compare benchmarks on these two related to video editing, if you can find them. Tom's Hardware (which is more gaming oriented) has a GPU tier list that I occasionally refer to, and it has the 1070 ti two tiers above the RX570, which would be a noticeable improvement.

Each GPU has different variants as well, so one more thing to keep in mind as far as performance goes.

I will say that with a RAW workflow, I really wouldn't skimp on any components. Especially hard disk space/speed and processor. The best GPU in the world won't help if the files can't be read fast enough off the hard drive.

It is an AMD GPU. I have no experience with the RX570 but my workhorse is using 2 AMD R9 390X GPU each with 8gb of RAM. I am very happy with those cards and I have no problems handling 4K RAW workflows. I've had my cards for 2 years now so I would think the RX570 will have newer tech, I just look at the benchmark to compare the RX570 with the R9 390X. It seems that the 390X has the better benchmark of the two, but a measly faster fps for the MRender test.

Resolve 14 and 15 now fully supports CUDA and Open CL so it's likely you will no longer have troubles with either an NVIDIA or AMD card. But you'll have to decide what gives you the best value for what you want to or can spend. I think if you are using your system as both for and gaming, then I suggest going with an NVIDIA card because there are probably more older games that requires CUDA. These days, it does not matter anymore. I use my workstation exclusively for editing and coloring so the AMD cards on my system are well suited for me.

That system sounds nice, but wouldn't a single 8gb R9 390X be enough to handle 4k RAW? My only goal is to use this with Resolve. I have a GTX 970 4gb that simply doesn't cut it for 4k RAW...

David,
Sorry for the late response. I started with a single and was able to render 4K RAW with not too heavy workflow - like only a few oFX and NR. The second card gave it much boost that I'm able to do so much. I don't know if you can mix AMD and INTEL cards but if you could then you can try using the R9 390X for your compute and the GTX 970 4gb for display.

From my experience, another bottleneck with 4K is the cache. A very fast storage (Multiple SSD RAID 0) for cache is equally important and don't short yourself on fast storage.

David, I run a 1070 in a 5960 tower and a 570 in a dual xeon tower. Most of my work is architecture so its all about cpu cores and base processor speed for me in raytracing. I do however edit 4k time lines a couple of times a month. The 1070 crushes the 570. If you are planning on 4.6 don't go less than the 1070ti. If I was going to have to do anything serious in the xeon I would pull the 570 and go minimally to a 1070ti. If I was working daily I would not be happy with anything less than a 1070 and truthfully I would run my monitors off the 1070 and get a 1070ti, probably a 1080ti for grading.

The 1070 is slightly slower than the 980ti I have in a a 5930 box in South America. The 5930 has a 970 to monitors and 980ti grading. Its was built 2+ years ago solely for photography and cine, works well in 4k raw out to about 5 nodes. Hope I answered your question.

It is getting crazy out there. There was a momentary sale yesterday at PCGAMER for about $370 for the 1070ti and $399 for a 1080. I am not a gamer so of course I heard about 6 hours too late but if you need a card its time to subscribe to the crazy card forums and see if you can catch one.
